A WARNING
If the engine stops while driving, you will
need to use more force to brake the vehicle.
This increases the risk of an accident. There
will still be power steering if the ignition is
switched on while the vehicle is rolling and
there is sufficient battery charge. Otherwise,
you must use greater force when steering.

(D Tips
-After starting a cold engine, there may be a
br ief per iod of increased noise because the
oil pressure must first build up in the hy­
draulic valve adjusters. This is normal and
not a cause for concern .
- If the . indicator light blinks in the instru­
ment cluster before switching the ignition
off, the ignition will not switch on again.

pa rking br ake
Requirement: The driver 's door must be closed.
.,. When you press the accelerato r pedal, the park­
ing brake is automatically released and your ve ­
hicle begins to move.
When stopp ing at a traffic signa l o r stopp ing in
city traffic, the parking brake can be applied . The
vehicle does not have to be held with the brake
pedal. The parking brake e liminates the tendency
to creep when a selector lever position is engag­
ed. As soon as you press the accelerator pedal,
the park ing brake releases automatically and the
veh icle starts to move.
St arting on slope s
When starting on inclines, the h ill start ass ist
prevents the vehicle from unintentionally rolling
back . The braking force of the parking brake is
not released unt il sufficient d riving force has
been b uilt up at the whee ls .
(0 Tips
For safety reasons, the park ing brake only re­
leases automat ica lly when the driver's door is
closed .
Emergency braking function
In the event that the conventional brake system
fails or locks .
.,. To brake your vehicle in an emergency, pull the
@ switch
q page 78, fig. 71 and hold it pulled.
.,. As soon as you release the @switch or acceler­
ate, the braking process stops.
Pulling and holding the@switch while driving at
a speed of about 2 mph (3 km/h) or h igher in i-
80
tiates the emergency b rak ing function . The veh i­
cle is braked at all four whee ls by activating the
hydraulic brake system . The brake performance is
s imilar to heavy brak ing.
q &
To he lp prevent activating the emergency braking
by mistake, an audib le wa rning tone (buzzer)
sounds when the @switch is pu lled . Emergency
braking stops as soon as the @switch is released
or the accelerator pedal is pressed.
A WARNING
Emergency braking should only be used in an
emergency, when the norma l brake pedal has
failed or the bra ke pedal is obstructed. During
emergen cy bra king, your ve hicl e will bra ke
similar to he avy braking. ESC and the asso ci­
ated components (ABS, ASR, EDL) canno t
overcome the laws of physics. In corners and
when road o r weathe r cond itions are bad, a
fu ll brake applicat ion can cause the veh icle to
skid or the rear end to break away, which in­
creases the risk of an accident.
Hill hold
App lies to vehicles: wit h Hill Hold
Hill hold makes it easier to start on hills.
Req uirement: The driver door must be closed and
the engine must be running.
The system is activa ted when the brake peda l is
pressed whi le the vehicle is statio nary .
To prevent the vehicle from roll ing ba ck when
st art ing, the brake power is held fo r a b rief mo­
ment afte r releas ing the b rake pedal. During this
time, you can easily begin to move your vehicle.
A WARNING
-The inte lligent technology of Hill Hold can­
not overcome the limitations imposed by
natura l physical laws. The increased comfort
offered by Hill Hold shou ld not cause you to
take safety r isks.
- Hill Hold cannot hold the vehicle in all hill
start sit uat ions (for example, if the ground
is s lippery or icy).

General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect d urability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it a lso calls for more concentrat ion from
the dr iver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements

check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system .
Safety chains
Always use s afe ty chains be tween your ve hicle
and the tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your Aud i dea le r fo r corr ect w irin g,
swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
